It was whilst flicking through Professor Alan S. C. Ross’s book ‘Don’t Say It’ that I stumbled merrily upon these two terms, which were both new to me. A pre-lactarian is someone who pours their milk into their tea or coffee before the hot water; a post-lactarian is someone who adds milk last.

But which method is correct? Well, there is no strict answer to this. It has its roots in class distinction.

In previous eras, adding the milk in before the hot water was always done by the ‘downstairs’ of the big houses, who would have pottery mugs. These mugs did not react too well to the boiling water, and thus the cold milk was poured in first so that it instantly cooled the water and thus the mugs survived in one piece.

Meanwhile, in the ‘upstairs’ of the house, where they could afford cups and saucers made from china or porcelain, the milk could be added after the hot water, as the cups were able to cope with the boiling water as they were made from a more resilient material.

As to who actually invented the terms pre and post-lactarian, I do not know and I am still researching, but they are much grander than some of the terms one could use instead!
